Is there anything wrong with the latest version（4.1.2）？

[zz-zheng-105]

It says “renamed 1.21.3 -> 1.21 WD and 1.21.2 -> 1.21.3 to match the Winter Drop”，but I can not find “1.21 WD” when I choose the game version.
（By the way，my game version is 1.21.1，which game version should I choose when I use cubiomes-views？）

If you click on "Edit" and then "Advanced world settings" you should see an option to "Enable experimentally supported versions".
This should enable you to select 1.21 WD

If you are running 1.21.1 without experimental features you dont actually need this though and should just select 1.21.3

The 1.21 WD is for the Winter Drop which includes the pale garden biome.
